IPC: F02C7/232
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To reduce a cost by simplifying a structure and reducing a space in an air supply system for gas turbine fuel nozzle purge. SOLUTION: Air in the compressor outlet of a gas turbine 1 has a temperature of 400 deg.C, is cooled by a first air cooler 20 so as to have a temperature of about 200 to 250 deg.C, and supplied from a piping 6 as a rotor cooling air. A part of air from the first air cooler 20 is cooled by a second air cooler 21 so as to have a temperature of 60 to 80 deg.C, eliminates drain from a piping 19 by a drain separator 11, increases its pressure by a booster compressor 13 from a piping 12 so as to be air having a temperature of 100 to 130 deg.C, and is supplied as air for purge from a piping 17. In the conventional case, air in the inlet of the booster compressor 13 was about 400 deg.C, therefore air had to be cooled by a cooler, and the temperature of air after increasing its pressure was also raised, therefore air had to be cooled by the cooler again.  However, in this case, air is cooled firstly by the second air cooler 21, therefore the temperature of air in the inlet of the booster compressor 13 is lowered, thus the cooler is no more required.

Title: Recording device
Inventor: MAKITA MASARU
IPC: B41J29/50
Filed: 1989-05-23
Abstract: PURPOSE:To automatically determine an appropriate line feed position for printing special characters by interpreting whether or not an area in which data are recorded following the first area belongs to an area in which data has been recorded in a previous stage based on a vertical position stored in the second storage device, and setting the lateral position for an area in which data is recorded following the first area based on the lateral position stored in the first storage device, if the area in which data is recorded following the first area belongs to the area in which data has already been recorded in the previous stage. CONSTITUTION:It is checked whether or not a vertical position for line feed is located in a vertical position for special characters. This check is intended for comparison of the vertical position for line feed with the content of a memory device (PVRAM)9 in which the vertical position for special characters is stored. If it is interpreted that a position for line feed is located at a current line and belongs to an area where special characters are printed, a lateral position is corrected. In this case, a target position for lateral movement, that is, a lateral position for special characters stored in a memory (PHRAM)8 for storing the lateral position for special characters as a lateral position for a line feed destination is determined. As a result of a change in the target position for line feed, CR1 feeds the line at a position P1. Next, vertical carriage position memory (VPMEM)5 and lateral carriage position memory (HPMEM)4 are updated with a line feed position as a carriage position.

IPC: F23N5/14
Filed: 1981-08-17
Abstract: PURPOSE:To decrease the time reaching a set temperature, by heating with a maximum combustion amount until the temp. attains a set temperature when a difference between the set temperature and a temperature sensor is a specified value or over, and performing proportional control afterward. CONSTITUTION:In a heating cooking apparatus, when a temperature of a temperature sensor 2 under a pan 1 and a set temperature 4 are a specified set value >=9 in the difference, a storage circuit 8 outputs a drive signal to a storage circuit 10. The circuit 10 outputs a signal keeping the maximum combustion amount of a burner 6 independently of the temperature of the temperature sensor 2 to a comparison amplifier 3. When the temperature of the temperature sensor 2 is equal to the set temperature, the circuit 8 outputs a signal releasing the keeping of the amount to the circuit 10 and the amplifier 3 controls a proportional valve 5 to the burner combustion amount in response to the difference between the temperature of the sensor 2 and the set temperature. Thus, when the temperature is lower than the set value at the start of heating, the time reaching the set value can be decreased.
